P.S. on searching for chars within a string

[larry at significantplanet.org]

Hi Craig,
Thanks for the tip.
I am using a for each loop and have run some benchmark time tests. I am able 
to find (match) the words I want in about 1/7 of the time that it used to 
take me using a different procedure - and the old way was pretty fast!  To 
find all the smaller words (length of 2 - 7) contained in a 12-ltr word, it 
used to take 3.46 seconds. Now it only takes 0.56 seconds. (finding 1698 
words)  And even better, the new way allows for getting the smaller words 
from a string of, say 30 chars, and it doesn't increase the time much - 
about 0.85 seconds for searching within 30 chars.  With the old way, I 
couldn't even search on more than 12 chars, because it just took too long.
So I learned a lot today!
Larry
P.S. Yes, I am using arrays.
